“Tricks, Treats & Boos…. Our boys’ Halloween Birthday!” Decked out in confetti and spiders, this blue brothers Halloween party invitation brings all the guests creeping over to your haunted house. We used a blue background for these brothers’ party, and two stars twinkled behind their optional photo. For your own design, we can tint your photo in spooky black & white and also recolor the text and background to your personal taste.
